SPRINKLER.

To all whom it' may concern.'

Be it known that we, WILLIAM H. STow and NELSON VICKERY, citizens of theUnited States of America, residing at Fennville, in the county ofAllegan and State of Michigan, have invented certain new and usefulImprovements in Sprinklers; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe Cri Our invention relates to improvements in sprinklers and moreparticularly to sprinklers for spraying fruit trees and 'the like, andits object is to provide a device having an extended tubular portionwith a nozzle at one end and suitable adjust-ing means for the same atthe other end, where by the nozzle may be operated at a distance fromthe operator; to provide improved means for controlling the spray andadjusting the same, and to provide the device with various new anduseful features, hereinafter more fully described and particularlypointed out in the claims.

Our device consists essentially of an eX- tended outer tube preferablyof bamboo or other like material, a pipe extending therein, means at oneend of the tube for longitudinally adjusting the pipe, and a sprayingnozzle at the other end adjusted by the pipe, and in various features ofcombination and arrangement, as will more fully appear by reference tothe accompanying drawings, in

which:

Figure 1 is an elevation of a device embodying our invention with aportion broken away from the middle of the same; Fig. 2 a detailpartially in section of the adjusting means at the lower end of thedevice; Fig. 3 an enlarged detail of the nozzle end in longitudinalsection adjusted for a widely scattered spray; Fig. 4 the same adjustedfor a narrow stream of the fluid; and, Fig. 5 a longitudinal sectionaldetail of the adjusting means.

Like numbers refer to like parts in all of the figures.

1 represents a tube of considerable length, preferably of bamboo orother like material.

2 is the hollow body of a nozzle attached to the upper end of the tube1.

3 is a removable cap to the nozzle having Specication of Letters Fatent.

a large central opening through which the spray is projected.

4 is a pipe preferably of metal in the axis of the tube 1 and movablelongitudinally therein.

5 is a sleeve rotative on the lower end of the tube 1 and inclosing acasing 17 fixed on the tube. This casing is provided with a spiralgroove 18 engaged and traversed by a lug 6 in the sleeve 5, whereby thesleeve is longitudinally adjusted by rotating it about the casing. Thelower end of this sleeve is lianged inward as at 5a, and within thelower end of the sleeve 17 is a longitudinally adjustable nipple 7having collars 8 and 8a engaging this inwardly turned flange 5a, wherebythe adjustment of the sleeve 5 will also longitudinally adjust thenipple 7. Attached to this nipple is a suitable hose 9 to bring thefluid to the device and communieating with any suitable reservoir offiuid under pressure, The end of the pipe 4 is fixed in this nipple andextends upward in the axis of the tube 1 and within the body 2 of thenozzle. 0n the upper end of this pipe is a hollow piston 15 having itsupper end perforated as at 16 to discharge the iuid, said piston beinglongitudinally adjustable in a tubular lining 10 with the nozzle, saidlining being preferably of glass to prevent corrosion by the chemicalsin solution, and having a small axial opening in its upper end as at 10ain which is adjusted a conical sprayer point 13 having a.circumferential shoulder 14. This point is carried on the piston andadjusted thereby. Within the upper end of the lining is a washer 12against which the piston 15 is forced to close off the flow of fluid anda packing 11 is provided between the end of the lining 10 and the cap toprevent iuid from escaping therebetween.

In operation, the nozzle can be placed among the branches of a tree, andthe operator stands on the ground. By turning the sleeve 5, the point 13is adjusted relative to the opening 10a. When retracted as in Fig. 4,the device will throw a solid stream to a considerable distance, andwhen adjusted as in Fig. 3, the shoulder 14 will deflect and scatter thefluid widely in a ne spray, and in intermediate positions, the spraywill be scattered more or less, according to such adjustment. It will benoted that this adjustment can be made while the device is in operation,and that by turning the sleeve to the limit, the end of the piston 15will be engaged with the washer 12, thus shutting off the iowaltogether. The lining 10 is also readily removed and replaced, asoccasion may require, and for some purposes, may be omitted entirely.

What we claim is 1. A sprayer, comprising an elongated tube, a nozzle atone end of the tube, a piston in the nozzle and having an openingtherethrough, a sprayer point mounted on the piston, a pipe attached tothe piston, a sleeve rotative and longitudinally adjustable on `thetube, and means for connecting the sleeve and pipe to longitudinallyadjust the pipe.

2. A sprayer, comprising an elongated tube, an adjustable nozzle on oneend of the tube, a pipe longitudinally movable in the tube and connectedto the nozzle, a sleeve rotative and longitudinally adjustable on thetube, a casing xed on the tube and having a spiral groove, a lug in thesleeve traversing the groove, and means for connecting the sleeve andpipe.

3. A sprayer, comprising an elongated tube, an adjustable nozzle at oneend of the tube, a pipe attached to the nozzle to adjust the same andextending within the tube, a nipple attached to the pipe, collars on thenipple, a sleeve surrounding the tube and having an inwardly turned angeengaged by the collars on the nipple, and means for longitudinallyadjusting the sleeve on the tube.

4. A sprayer, comprising an elongated tube, an adjustable nozzle at oneend of the tube, a pipe connected to the nozzle to adjust the same, anipple attached to the pipe, collars on the nipple,asleeve rotative onthe tube and having an inwardly turned flange between the collars, acasing surrounded by t-he sleeve and liXed on the tube and also having aspiral groove, and a stud in the sleeve engaging and traversing thegroove.

5. A sprayer, comprising an elongated tube, a nozzle having a removablelining provided with a small axial opening at the end, a piston movablein said lining and having an opening therethrough, a sprayer pointhaving a circumferential shoulder and movable longitudinally within saidopening, said point being mounted on the piston, and means forlongitudinally adjusting the piston and point.

6. A sprayer, comprising a case, a removable cap on the case having alarge end opening, a lining in the oase retained by the cap and having asmaller end opening, a piston adjustable in the lining, a sprayer pointadjustable in the said openings and carried by the piston, means foradjusting the piston in the lining, and means for supplying fluid to thespace between the piston and 6 said opening.

In testimony whereof we aix our signatures in presence of twowitnesses.
